Add rungs to ladders

“

- [Instructor] We're staying in the demo 10.DWG file in the WD demo project and what we're going to do now is look at adding some rungs to our ladder. I can guarantee when you're working in your electrical drawings your ladders will never be long enough and never have enough rungs, so you need to add a rung to the ladder and renumber accordingly and maybe add a rung to go across between the two reference points on the ladder as well. So we're still zoomed in at the top of our ladder right now, up at 1000 and there's one of the wires that I added in the previous video. So I'm just going to roll back on the wheel a little bit, pan upwards and zoom in on the bottom three or four rungs of the ladder like that. So you see at the moment our ladder is ending at that 10 11 reference point. Now what I want to do is I want to add a new reference at the bottom of that so that we've got 10 12. So what we do there is go to the schematic tab on the ribbon and enter the edit wires wire numbers panel. And I'm going to click on this little fly out menu here and you can see that we can add a rung, we can revise a ladder, or we can renumber our ladder referencing if we want to. You want revise ladder first, okay. Now at the moment, our rung spacing is 0.75 of an inch, it's an imperial drawing, the rung count is 12, and the reference start is 1000. Now the index is one, which means it's like 1000, 1001, 1002 and the wire number format there is basically percent end. So it's just showing the number of the wire there on the ladder. Now I'm going to change the rung count to 13. So I'm adding an extra rung, so when I click on okay, what you'll find is the reference appears. There's the 10 12 that I wanted. Now what we need to do is in order to add our rung going across we need to extend our ladder. So I just click here, click on the grip, drag it down a little, take it down to that point there. Hit escape, deselect, do the same the other side, click on the grip again and come down, and again these don't have to be perfect but I've just tried to make sure that they match there so I'll hit escape so they kind of match going across. It doesn't matter as long as they intersect with our 10 12 here. So now I go back up to edit wires and wire numbers, click on the same fly out again and select add rung. So this adds a ladder rung at the line reference nearest to a point you select inside the ladder so you can see there with the little diagram this 402 and then there's the red wire 402 going across. Click on add rung and then taking your crosshair, line it in so it's near the 20 12 but it has to be inside the ladder vertical line so if I just click about there, you'll see there's my extra rung on my ladder. Now the good thing is you can add as many as you like because what you could have done there is taken that number of rungs to a much higher number, dragged the lines down further, the vertical lines, and added even more rungs if you wanted to. But that's how quick and easy it is to add a rung to an existing ladder in your AutoCAD schematic drawings in AutoCAD electrical. Just hit escape a couple of times to make sure though that you have come out of the command as well. But that's how you add rungs to your ladder, nice and quick and easy.
